摘要:
为探究渝北区未来存量用地的挖潜方向,通过构建商服圈,并利用建筑、人口经济、交通和公共服务设施数据,从功能、强度和区位潜力3方面选取评价指标,结合层次分析法和熵权法确定其权重,计算渝北区城镇建设用地集约利用潜力,并依此识别可用于二次开发的宗地.结果表明:①渝北区划定商服圈总面积15 827.25 hm2,因受地形、政策和城市双核心发展因素影响商服圈呈不规则形状;②用于潜力评价的宗地因城市开发过程中各类用地并存且未实现更新而未呈现同心圆模式;③渝北区可用于二次开发的城镇建设用地总面积为1 178.88 hm2,主要布局于两路老城区南部、龙山-龙溪-龙塔街道西北部和创新经济走廊中部等区域.④渝北区公共管理与公共服务用地和商业服务业设施用地土地集约利用潜力较大,是未来改造盘活的主要用地类型.

Abstract:
The purpose of this study is to explore how to exploit the stock land in Yubei district in the future. First, using the building data, demographic and economic statistics, traffic data and the public service facility data on the stock land, we select the assessment indexes from the three aspects of potential in function, intension and location. Then, using the AHP and the entropy method in combination to determine the weight, we calculate the potential of intensive use of urban construction land in Yubei district and, based on the result, recognize the stock land which can be reconditioned. The results show that the area of the circle of business services in Yubei district is 15 827.25 hm2 and, influenced by the landform, policy and the dual core developing history, the shape of the circle is irregular; that the pattern of the parcels used to assess the intensive potential of land use is not a concentric-circle structure, because the coexistence of various kinds of land use remains unchanged; that the total area of the urban construction land which can be reconditioned in Yubei district is 1 178.88 hm2, and it lies mainly in the south of Lianglu old town, the northwest of Sanlong street and the central part of the Innovation Economy Corridor; and that land to be used for public management services and land for business services facilities in Yubei district have relatively great intensive use potential, and they are the main types of land use which can be reconditioned.
Key words:  parcel-land scale  intensive land use potential  stock land  Yubei district
